Lab 1: Introduction to SPSS
You must attend your registered lab. A Lab Results Sheet will be given to you at the
beginning of your registered lab (and not before). This must be completed and handed in
before you leave at the end of your registered lab.
1. Log in to the computer using your SFU computer ID and password. Your
personal drive space (H:/) will automatically be mounted.
2. Download and save to your personal drive space the grip.xlsx file from
the course web site.
3. Open the MS EXCEL application and use it to open the grip.xlsx file.
Recommend you do not open the file by double clicking the file icon in the folder.
4. In the grip.xlsx file, modify the variable names to include units, then delete
the second row of the file.
e.g.
Grip max Right
kg
becomes
Grip max Right kg
5. Save the file with the new name gripnew.xlsx.
6. Open SPSS and open the same gripnew.xlsx file.
7. Save the data file in the SPSS .sav format as grip.sav
8. Go into Variable View of the SPSS Data Editor and assign the missing
value 99 to each of the strength, length, girth & skinfold variables. Also
assign variable labels (on next page) and value labels (where
appropriate) to each variable. E.g. SEX: Sex of Subject, 1 = Man, 2 =
Woman
9. Using Split File from the Data menu list, group the data for future analysis
split by the SEX variable.
10. Using Compute from the Transform menu list, create a new variable
which is the difference between right and left max grip strengths. Assign a
variable label to this new variable.
11. Using Descriptive Statistics from the Analyze menu list, select the
Descriptives option and select each of the right and left max grip
strengths, hand lengths, forearm girths & forearm skinfolds for analysis
(there are 8 variables total). With the split file by sex on, using the
Options button on the Descriptives dialogue box select the mean,
standard deviation (SD), standard error of the mean (SEM), and
coefficient of skewness as the statistics to calculate. Complete the Lab
Results sheet from these calculated statistics.
12. Save the grip.sav SPSS file in a safe place, for possible use later in the
course.
